Preliminary data also shows signs that some buildings along the coasts of Broward and Palm Beach are sinking, too.

Nearly three dozen luxury hotels and condos at Miami are sinking into the ground at an “unexpected” rate, according to a study by the University of Miami. The study found 35 buildings — roughly 70 percent of the buildings in the northern and central Sunny Isles — sunk by as much as three inches between 2016 and 2023.
